Language and Education invites the reader to experience a journey through countless relations between language study and education. Starting from the point of view of language, its social context and transmission, this book examines some common concepts related to education as an activity: “language”, “dialect”, “variety”, “ register” and even “mother tongue”, “second language”, “foreign language” and “bilingual intercultural education”, among others. This concepts are analysed according to the role of education in the process of “producing language” as a political, cultural and ideological matter. Throughout the chapters of this book, it is possible to review some key linguistic concepts from the educational perspective (how we learn languages, what characterizes and differentiates oral and written use of the language, what is writing and how it is learned, how is language used in class and its learning rol, etc.) as well as to acknowledge the contributions of sociolinguistics applied to the comprehension of educational processes, its contexts and results.
